SYNTHETIC PERFUME. I

No Drawing.

My invention relates to improvements in,

synthetic perfumes, flavoring extracts and similar synthetic materials.

Synthetic materials have become of considerable commercial importance in the art of manufacturing perfumes, flavoring extracts and allied products. However, the materials heretofore used in manufacturing synthetic perfumes, flavoring extracts and the like have been made from chemicals that are expensive to produce by reason of the complicated and tedious processes which are employed. As a result of these expensive processes, such materials as synthetic perfumes and extracts, have sold at excessively high prices.

By means of my,present'invention, I provide a synthetic perfume or flavoring extract'which will be economical to produce. My present invention contemplates the use of furfural and'its derivatives, such as pyroinueic acid, furfur alcohol and furfuracrylie acid as the source from which synthetic flavoring extracts and perfumes may be produced which possess essentially new and highly desirable properties.

In accordance with my present invention, I :procure synthetic materials of the character indicated above directly from furfural as well as from its derivatives, such as pyro' mucic acid, 't'urfuralcohol and fin'furacrylic acid. I have discovered that esters formed from pyromucie acid and the aliphatic al cohols are especially desirable as materials for synthetic perfumes, synthetic flavoring extracts and the like. I" have prepared a considerable number of furfural derivatives, such as the. methyl, ethyl, propyl, butyland amyl-pyronuicates. allot which have distinctive odors and flavors of thoqualitics highly desired as flavin-ing extract. and perfumes. Since these esters" may he very easily prepared and since the raw materials for their manufacture are quite inexpensive, synthetic. perfumes and extracts embodying my invention-may he sold much cheaper than '-oi.'res 'ion( ling synthetic materials heretofore rn'oduced- In view of the highly characteristic flavors and odors of the foregoing furfural derivatives, I am also able to extend the range of flavorin and perfume materials considerably beyond that hereto- -Ap'p1ication filed December 26, 1922.

fore attained with synthetic materials procured from other chemicals.

The following process I have employed for producing the-esters of pyromucic acid and particularly ethyl pyromucate. To 11.2

' tion. This ethyl pyromucate has a highly pleasing and delectable odor and may be employed as a material for a synthetic perfume or flavoring extract. V

It is to be understood that my invention is not "'t o be limited in its scope except by the prior. art and the limitations defined in the appended claims.

IVhat I claim as new and desire to secure by Letters Patent of the U. S. is

l In the art of'perfuming, flavoring and the like, the employment of a furane derivative as the pe'rfun'ling, flavoring or like agent.

2-. In the art of perfuming, flavoring and the like, the employment of an ester of pyromucic acid as the pertaining, flavoring or the like agent.

In the art of perfuming, flavoring and the like, the e 'nployment of ethyl pyromucate as the per-fuming, flavoring or the like agent.

4. In the art of perfuming', flavoring and the like, the employment of an ester of pyromucic acid in :ltlll'llXtlll'Q with an aliphatic alcohol as the perfuming, flavoring or the like agent. i

Ii. In the art of perfui'ning, flavoring and the like, the employment of an ester of pyrollllJClC acidin admixture with an aliphatic alcohol or the paraflin series as the perfuming. flavoring or the like agent.

6. In the art of per-fuming, flavoring and the like, the employment of a compound of an acidic furane derivative as the perfuming, flavoring or the like agent.

In witness whereof, Ihave hereunto sub-'
